Section 22 Serial Communication Interface with FIFO (SCIF)
(2) Clocked Synchronous Mode
• The transmission/reception format has a fixed 8-bit data length.
• In receiving, it is possible to detect overrun errors (ORER).
• An internal or external clock can be selected as the SCIF clock source.
 When an internal clock is selected, the SCIF operates using the clock of the on-chip baud
rate generator, and outputs this clock to external devices as the synchronous clock.
 When an external clock is selected, the SCIF operates on the input external synchronous
clock not using the on-chip baud rate generator.
